Title: Developing cartridge
Inventor: TONOMOTO YOSHIHIRO
IPC: G03G15/09
Filed: 1987-04-20
Abstract: PURPOSE:To obtain printing having sharpness and stability from immediately after the replacement of a developing cartridge, by forming a developer containing part in the developing cartridge by two boxes, containing separately a toner and a carrier, and preventing a deviation by both of them. CONSTITUTION:A developer containing part 13 is constructed so that it is formed by two boxes A, B by partitioning it by a partition plate 16, and a toner of a developer and a carrier are put into its one A, and the other B, respectively, and a deviation is prevented by both of them. For instance, in the box A, the toner is put, its filling rate is set to >=80%, and a deviation of the toner is prevented by the filling rate in the same way as conventional device. Also, in the box B, the carrier is put so as to sprinkle averagely over a magnet roller 11, and the carrier is adsorbed and fixed uniformly to the developing magnet roller 11 by magnetic force. Accordingly, it does not occur that the carrier is deviated due to vibration, etc. In such a way, by containing separately the toner and the carrier, it is prevented that the developer is deviated due to a difference of the specific gravity of the toner and the carrier as conventional device, and a uniform image is obtained.

Abstract: The present invention concerns a procedure for removing gases from a distilling apparatus (10). In the procedure, the effluent water is caused to flow from the distilling apparatus (10) along an effluent line (19) to an effluent heat exchanger (13) for recovering the heat contained in the effluent. The feed water is arranged to flow along a first branch line (14a) through a distillate heat exchanger (12) and along a second branch line (14b) through the effluent heat exchanger (13) to the purpose of preheating the feed water. The mixture of distillate, vapour and gases is conducted from the distilling apparatus (10) along a flow line (16) to a degassing heat exchanger (11), where the heat contained in the mixture is recovered. The recovered heat is utilized in preheating the feed water by conducting the feed water after the distillate heat exchanger (12) and the effluent heat exchanger (13) along a header line (15) through the degassing heat exchanger (11), and further by a tubular connector (20) into the distilling apparatus (10). The gases are allowed to escape from the degassing heat exchanger (11) through a gas venting hole (17) into the environment. The mixture flow is condensed in the degassing heat exchanger (11) to distillate, and the distillate is conducted from the lower part of the degassing heat exchanger (11) along a distillate line (18) to the distillate heat exchanger (12).

Title: Production of silicon carbide single crystal
Inventor: SUGIYAMA NAOHIRO
IPC: C30B29/36
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a silicon carbide single crystal by imparting a temperature gradient to the inner portion of a silicon carbide single crystal having a cubic form and further heating a high temperature portion in the single crystal at a specific temperature to transform the cubic form, capable of easily obtaining the SiC single crystal scarcely having defects and having a high quality. SOLUTION: This method for producing a silicon carbide single crystal comprises imparting a temperature gradient of >=0.5 deg.C/mm to the inner portion of a cubic silicon carbide single crystal and heating a high temperature portion in the single crystal at a temperature of >=2,100 deg.C. The temperature gradient is >=1 deg.C/mm. The cubic form of the single crystal is thereby transformed into a hexagonal form. A device for imparting the temperature gradient to the single crystal and further heating the single crystal at a high temperature uses a conventional heat-generating belt and a control device therefor.  The heating is carried out by heterogeneously heating a fixed silicon carbide single crystal to impart a temperature gradient or by relatively moving a silicon carbide single crystal to a fixed heat generator to successively heat the local portions of the silicon carbide single crystal, thus imparting the temperature gradient.
